    This is something we've implemented in numerous settings. Yet, there are a number of factors to think about. In our experience, it is crucial that the heating system be installed at the same level as the final floor. Our experience has shown that the seed spread over the underfloor heating is often uneven, making installation challenging.

    Underfloor heating and wooden floors are a common and successful combination. Hardwood flooring made by Kährs can be installed over either an electrical or hot-water subfloor heating system. The underfloor heating system supplier's advice and our own detailed installation instructions should not be disregarded.

    An expertly laid wood floor will not only look great and last for years, but it will also be warmer and cosier underfoot. In this article, you will find guidelines and recommendations for selecting the best underfloor heating for your hardwood flooring.

    Your wood floor must be installed without an air gap and in close proximity to the subfloor to prevent the wood from drying out too rapidly.

    Working temperatures of at least 18 degrees Celsius are recommended while installing flooring over underfloor heating loops. Boards, subfloors, and ambient temperature all fall under this category. Before, during, and after floor installation, the relative humidity (RH) of the air must be between 30 and 60%.

    Since cardboard has a lower thermal conductivity than polythene cellular plastic or cork particleboard, it is the material of choice for the intermediate layer.

    Important Details Regarding Floor-to-Ceiling Heat Pumps

    • To avoid localised heating, the floor structure must have a heat-distributing layer that maintains a consistent temperature across the entire floor area.
    • Accurate surface temperature regulation and restriction must be possible.
    • All of the space on the floor needs to be warmed. Comfort heating systems, which are supplementary to primary heating, are exempt from this. The temperature should be significantly lower than the maximum 27 degrees Celsius allowed on the floor.
    • It's important that the entire floor, including the in-between layer, has a low thermal resistance.
    • To prevent moisture from seeping through the wood below, a vapour barrier should be installed during the flooring's construction. If the joists are thick or heavy, it is especially vital to install the vapour barrier close to the wood floor. The vapour barrier must never be installed on the stud side of the joists.

    Whether you're doing a modern remodel or a period restoration, timber flooring is a great choice because it looks great and works well with underfloor heating. At HP Constructions, we have the best home construction selection to make your house a dream come true.

    When compared to conventional central heating, underfloor heating can have much reduced operational costs.

    Frequently Asked Questions About Home Renovation

    Is it cheaper to renovate your house, buy a used one or build a new one? A: It's almost always less expensive to renovate an existing house than to buy used or build a new one. It's easiest to break the numbers down by square foot, keeping in mind that costs are highly variable based on location and market shifts.

    Chances are, the cost of buying a brand new property will be higher than that of a renovation project.

    The module follows Google guidelines and adds FAQ schema.

    Kitchens and bathrooms are by far the most popular rooms to renovate. Kitchens have consistently topped the list, with bathrooms close behind. Generally speaking, kitchens and bathrooms are popular to renovate because they make a noticeable aesthetic and practical improvement.

    It's best to start with the kitchen because these remodels add significant value to your home. According to the National Association of the Remodeling Industry's 2022 remodeling impact report, Realtors estimate that homeowners can recover 75% of the cost of a complete kitchen renovation if they sell their home.

    The Best Flooring To Have With Underfloor Heating

    can you install timber flooring over underfloor heating (3)

    Tile or stone flooring are preferable since they are very efficient heat conductors. These floors are also great at retaining heat, so even if the thermostat is turned off, you can still feel the warmth. If heat loss is a concern, installing a tile or stone floor in a room with plenty of windows is a good idea (conservatories, for example).

    Features Heated Floorboards Made of Solid Wood

    However, solid wood floors are not a strong conductor of underfloor heating, therefore they are not a great choice for those who want to use this heating method. If you want the same result as tile or stone flooring, you will need to turn up the heat and keep it on for longer. However, due to the fluctuating moisture levels in the wood, underfloor heating should not be set higher than 27 degrees Celsius when solid wood is installed above it.

    Heat fluctuations affect the wood's moisture content, which in turn causes the solid wood to bend and move.

    Underfloor heating and engineered wood floors.

    Instead of installing under-floor heating, go with engineered wood floors if you're set on a wood floor. Because of its special treatment and manufacturing process, this flooring type is far more responsive to temperature variations. Engineered wood flooring is both thick enough to be a beautiful wood floor and thin enough to allow heat to easily rise from the floor.

    For optimal results with underfloor heating, it is recommended that you pick a wood flooring type that has been approved for such usage by the manufacturer.

    Considerations for Installing Wood Floors Above Radiant Heat Systems

    The combined thermal resistance of a wooden floor and underfloor heating should not be more than 0.15 m2 K/W. If your floor has a high thermal resistance, warming it up will take longer and your underfloor heating won't be as effective.

    Quick-Step Timber's thermal resistance can be found in dedicated underfloor heating recommendations.

    An insulating layer superior to the timber floor should be installed below the heating system. This prevents heat from being absorbed by the insulating layer and instead sends it through the floor.

    Hardwood Floors and Radiant Floor Heating

    Similar to how underfloor heating works, but with cold water, floor cooling employs the same principles. A sophisticated management and security system is necessary for underfloor cooling to prevent internal dampness because the system cools down your floor. If you do this, water won't be able to penetrate your floor.

    Floors with a thermal resistance of 0.09 m2K/W or less are recommended for use in floor cooling systems. About 0.14 m2K/W is the heat resistance of 14-millimeter Quick-Step Timber. As a result, some capacity reduction is inevitable.

    Putting in a heated timber floor.

    Quick-Step The two most common methods of laying a wooden floor are the glue down and the floating methods. Glued-down flooring is a little improvement in heat transmission. Unless otherwise specified in the underfloor heating installation instructions, the standard installation procedures remain in effect. If you have any questions, it is best to ask your dealer.

    Putting up Wood Floors Over Radiant Heat Systems

    Do you plan to use the wood flooring over the heated subfloor? Keep in mind that solid wood flooring is not suitable for use with underfloor heating, so you'll need to select engineered wood instead. There is a large selection of engineered wood flooring available in many various styles and finishes.

    You may recall from our prior articles that engineered wood, also known as composite wood, is composed of two or more layers of wood or plywood that have been adhered together to form a plank. Since wood serves as the top layer of this flooring, it exudes a stunningly natural and beautiful aesthetic.

    In comparison to solid wood flooring, engineered wood is far more sturdy and can be used for laying a wood floor over underfloor heating. Gapping, cupping, and crowning are all issues that can arise with solid wood flooring because of its lack of stability. Significant changes in humidity and temperature might have a negative impact on its performance.

    Radiant Floor Heat

    Let's talk about underfloor heating now because that's the next big decision you'll have to make in relation to your floors. Wood flooring installed over underfloor heating requires a different installation process depending on the heating system. There are two primary types of systems available to you: wet and electric.

    Radiant Floor Heating using Electric Elements

    A heating element is what actually does the heating in electric underfloor heating systems. Flooring must be floated for this form of underfloor heating. In this scenario, the prefered method of installing a floor is one in which it is not nailed or glued to the subfloor. Instead of being fastened directly to the subfloor, the individual planks in this method are joined together with glue, nails, or snaps.

    The usage of an underlay is customarily part of the floating installation method. For the best results, talk to an expert about which underlay to use if you plan on using the floating installation method and want to add padding. The underlay must be appropriate for the floor being installed.

    Using Water for Floor Heating

    Wet underfloor heating is a form of floor heating that use a water-based heating technology. Connecting it to a stove, fireplace, or other source of heat is therefore not a problem. As such, it is suggested that the flooring be affixed directly to the monitor using glue. To provide for the expansion and contraction of the floor as a result of variations in humidity and temperature, engineered wood floors should be glued down during installation. The glue's adaptable nature allows for this to happen. Moreover, air pockets, which can often form when flooring is laid above underfloor heating, can be avoided with bonded flooring.

    Wood floors can be installed over under-floor heating with little effort. Nonetheless, anyway, we'd advise you to double-check everything if you're not sure, and always consult a professional for information on the best technique of installation and any other additional recommendations you may need down the road. Finally, remember to always follow the guidelines provided by the underfloor heating and flooring manufacturers.

    The Benefits of Wood with Radiant Floor Heating.

    Because it is a natural material, timber responds to its immediate surroundings in specific ways, and this must be taken into account when installing an underfloor heating system in a home with timber flooring.

    Superior Depth

    We propose that the thickness of the wood be no more than 18mm since the density and thickness of the wood can affect the functioning of the system. A thickness-to-width ratio of 7 to 11 is also recommended, as wider timber boards tend to exhibit greater movement than narrower ones. A 16mm thick board that is 160mm wide is perfect because the ratio is 10.

    Rheological Properties of Materials

    Although it is generally advised that the surface temperature of a wooden floor not exceed 27 degrees Celsius, this is technically incorrect. This temperature recommendation stems from earlier studies that measured the expansion and contraction of timber flooring, finding that the expansion of timber examined was 'invisible' to the naked eye at 27 degrees Celsius.

    It is now recommended that timber floors be heated to this level, but it is possible to heat them further if necessary. Flooring should be kept at a maximum of 27 degrees Celsius unless otherwise directed by the manufacturer.

    An underfloor heating system can be precisely controlled by a Warmup Thermostat to ensure the timber floor doesn't get too hot. Always have a heat loss calculation done as part of your project to guarantee that the underfloor heating system will be enough for the space.

    Growth and Decline

    Timbers and engineered wood will both expand and contract naturally over time due to the hygroscopic nature of all wood. The moisture content of your timber for your floor-heating project may change based on the species you select and the climate in which you're working. A wooden floor will expand and contract somewhat throughout the year due to seasonal fluctuations in humidity. The responsiveness of a floor heater might be affected by the natural expansion and contraction of wood floors if they are not properly fitted.

    Installing New Radiators in Existing Wooden Flooring

    Many older houses have floors made of suspended timber, and we provide a variety of floor heating systems that are optimised for this type of flooring. We have a wide range of Melbourne timber repairs for your home renovations. Check out Hitch Property Constructions.

    Supply Networks

    Installing a floor heater in an older building that still has its original flooring rather than a new timber floor finish might be a challenging undertaking. A system can be retrofitted either from the top down or the bottom up.

    Water systems typically necessitate the removal of all timber flooring on the ground floor prior to installation, with the flooring being reinstalled after the heating system has been put in place. For a first- or second-floor timber floor, retrofitting from below is advised, which entails removing the ceiling in the room below to make room for the heating system's installation.

    Suspended wooden floors are ideal for wet underfloor heating, and the Tectoria Joisted Batten System is the ideal way to install it. The insulation panels and water piping for the underfloor heating system are installed in the gap between the floor joists. Keeping the warm air in and the cold air out requires an airtight underfloor heating system, which you should be aware of.

    Energy Supply Methods

    Suspended wooden floors can also be heated with electric underfloor heating. Still, in such circumstances, the original timber floorboards would be used as a subfloor, and the electrical system would be installed on top of that before the new flooring finish was laid.

    Tips for Setup

    There are a few crucial considerations for a first-time, problem-free installation of an underfloor heating system in a room with a fresh wooden floor.

    Timber Acclimatization

    The timber flooring should be allowed to acclimatise to the atmosphere inside the space it will be fitted to because of the moisture content of the timber and the influence this has on growth and movement. The method includes a heating cycle during installation, during which the floor surface temperature should be maintained at 15°C and the air temperature between 15°C and 22°C. Optimal relative humidity ranges between 40-60%.

    The flooring system should be turned off for at least 48 hours after installation to allow the floor to acclimatise. Keep the floor at a maximum of 15 degrees Celsius, and raise it by 1 degree Celsius per day until the appropriate temperature is reached. Given that the average temperature in a room varies throughout the year, it's smart to double-check the temperature constraints with your floor's manufacturer. While installing heated flooring, it is important to verify the manufacturer's recommendations.

    Advice for Screeding

    When installing underfloor heating with a timber floor, it is important to remember that the screed will provide additional moisture to the timber due to its hygroscopic qualities. Thus, it is suggested that the screed be allowed to dry at a pace of 1mm each day. If you want to avoid issues with the expansion and contraction of a wood floor in the future, leave a 10mm expansion gap around the room. Looking for home renovations Melbourne? Look no further!

    The Finest In Radiant Floor Heating For Wooden Flooring

    When it comes to water underfloor heating, nothing beats the Tectora Joisted Batten System for floating wood floors. Its piping and insulation are concealed within the space between joists, and its aluminium diffusion plates disperse heat uniformly throughout the floor's wood surface.

    • Our Total-16 system is another excellent hydronic option; its low profile construction makes it ideal for restoration jobs where additional floor height is not desirable.
    • Foil Heater is an electric underfloor heating system with a special design that allows for quick installation, making it an ideal choice for floating timber floor finishes.

    It is important to select flooring that has strong conductivity if you want to install an underfloor heating system in your home that works well and saves you money. This allows the floor's radiating heat to quickly warm the room below.

    For the same effect, underfloor heating would need to be set to a greater temperature for a longer period of time if the flooring were carpet rather than tile.

    Conclusion

    Underfloor heating and wooden floors should be installed at the same level as the final floor, with working temperatures of at least 18 degrees Celsius, accurate surface temperature regulation and restriction, and a vapour barrier installed during construction. Timber flooring is a great choice for underfloor heating, but it should not be set higher than 27 degrees Celsius due to fluctuating moisture levels in the wood. Underfloor heating requires an insulating layer below the heating system to prevent heat from being absorbed by the insulating layer and instead sending it through the floor.
